11. BYRSONIMA Rich.; A. Juss. Ann. Mus. Paris 18 : 481. 1811. 



Shrubs or trees, usually with white or colored pubescence, at least on the young parts, 

 or sometimes woody vines. Leaves opposite, glandless ; blades narrow or broad, entire, 

 usually thick, sometimes veiny-reticulate, sessile or petioled. Flowers in terminal raceme- 

 like panicles. Calyx with 10 glands, or glandless ; sepals 5, broad, persistent, sometimes 

 markedly accrescent, the glands large, sessile. Corolla yellow or red ; petals 5, the blades 

 suborbicular to reniform, strongly concave, undulate, toothed, or incised. Stamens 10, all 

 anther-bearing ; filaments short, slightly united at the base, often pubescent ; anthers 

 long, linear, oblong, ovoid or obovoid, sometimes with a conspicuous connective. Ovary 

 3-lobed. Styles 3, slender. Stigmas subulate. Drupes ovoid to globose, often yellow, 

 orange or red. 



Type species, Malpighia spicata Cav. 



Connective shorter than the anther-sacs, or about equaling them. 



Bracts small, mostly less than i mm. long, silky on both sides, but more 

 densely so beneath, during anthesis. 

 Leaf-blades of an oval, oblong, elliptic, obovate, or ovate type, pin- 

 nately veined. 

 Leaf-blades relatively broad, only slightly longer than wide, not 

 narrowed at the apex ; flowers and fruits stout-pedicelled. 

 Leaves, panicle-rachis, bracts, pedicels, and sepals copiously 



pubescent; anthers obovoid. 1. B. Berteroana. 



Leaves, panicle-rachis, bracts, pedicels, and sepals glabrous or 

 with scattered hairs ; anthers ovoid. 2. B. glaberrima . 



Leaf-blades relatively narrow, much longer than wide, narrowed at 

 the apex; flowers and fruits slender-pedicelled. 

 Leaf-blades glabrous, inconspicuously veined, scarcely paler 



beneath than above. 3. B. coriacea. 



Leaf -blades somewhat pubescent beneath, conspicuously veined, 



decidedly paler beneath than above. 4. B. spicata. 



Leaf -blades of a spatulate or cuneate type, finely reticulate-veined. 

 Panicle-rachis elongate ; bracts about twice the length of the 



bractlets ; blades of the mature leaves flat. 5. B. lucida. 



Panicle-rachis short ; bracts and bractlets about equal ; blades of 

 the mature leaves strongly revolute. 6. B. biflora.
